Answer:
XV = 4.75
Step-by-step explanation:
TV/WV = UV/XV (similarity theorem)
TW = 9
WV = 3
UV = 19
TV = 9 + 3 = 12
XV = ?
Plug in the values
12/3 = 19/XV
4 = 19/XV
XV × 4 = 19
XV = 19/4
XV = 4.75
a f(a) is the function f(x) where x is replaced by a.
So we have
(3x^2 + x + 3 - (3a^2 + a + 3)) / ( x - a)
= (3x^2 - 3a^2 + x - a) / (x = a) Answer
b (3(x + h)^2 + x + h + 3 - (3x^2 + x + 3)) / h
= (3x^2 + 6xh + 3h^2 + x + h - 3x^2 - x - 3) ) / h
= (6xh + h + 3 h^2) / h
= 6x + 3h + 1 Answer
